- WILL (580 AM) is a public broadcasting station owned by the University of Illinois Urbana-Champaign and licensed to Urbana, Illinois, United States. It is operated by Illinois Public Media, with studios located at Campbell Hall for Public Telecommunication on the university campus. WILL is directional, mostly to protect co-channel WIBW in Topeka, Kansas. It operates with 5,000 watts during the day, and due to its location near the bottom of the AM dial, as well as its transmitter power, directional antenna and central Illinois's flat land (with high ground conductivity), this provides grade B coverage as far north as Chicago and as far east as Indianapolis. At sunset it must reduce power to 500 watts and gradually power down to 100 watts, resulting in marginal coverage even in Champaign-Urbana. At 6 a.m., it increases its power to 335 watts and ramps up to full power at sunrise. (en)
